The quality of the data can be higher in observational or experimental studies depending on the subject being researched.
In a way, we can think that experimental studies have better data quality, due to the design of the experiment and the control of the study groups and the variables that are not possible to be established in the obsevational experiments.
However, in the case of studies of abstract subjects, the experimental study ceases to provide high quality activities, and it is necessary to establish an observational study so that efficient data can be promoted.
